High temperature latent heat storage device, especially for use in space, comprises graphite or ceramic container brazed to lid by a gold- or copper-based active brazing material

摘要

Latent heat storage device comprises a graphite or ceramic container (12) brazed to a lid (42) by a gold- or copper-based active brazing material. An Independent claim is also included for a method of filling the above latent heat storage device. Preferred Features: The container (12) and the lid (42) consist of uniform isotropic graphite with a pyrocarbon internal coating and a silicon carbide external coating.
